Passing the Parameter while calling the Data Pipeline using REST API

Hi 12_shashank​,

The body needs to contain an executionData element. 

Also ensure that your jobType is Pipeline. 

POST 

https://api.fabric.microsoft.com/v1/workspaces/{WorkspaceID}/items/{ItemID}/jobs/Pipeline/instances

{
  "executionData": {
    "parameters": {
      "config_file": "excess"
    }
  }
}

Here is the body I used: 

{
  "executionData": {
    "parameters": {
      "Subject": "Test",
      "Body": "This is a test"
    }
  }
}

and in the service here is the pipeline run with those parameters:
